    Carbo, that thought has gone through my mind more then once

    OG, not sure I understand your question?

    Jay, how long have you used it and do you apply it right to the gel bottom?

    Been using Hullkote for a few years - it is a relatively new product. I use it on my Laser, Vanguard 15 and the Thistle - all small, drysailed one-designs.

    McLube Sailkote spray has been around for 10 years or so and is great for anything that slides or spins especially if the boat is used in saltwater.

    Even though sunshine is sparse, I laid out the color chips to at least eyeball them. Even with a lousy cell camera, easy to see the major difference. Question for those who have the experience with gelcoating, how does one add "pearl" to a given color and what does it actually do?

    I can't answer your question, I'm totally clueless.
    But what's that white stuff on the ground?
    Where I am doesn't look like that.

    You might need to consult with a gelcoat manufacturing company to make sure pearl will still create the effect in gelcoat that it does in paint. In the case of automotive paints, it takes very little to create the effect - too much and it will look like a glazed ham going down the highway as a friend of mine once explained - lol. Bill

    I agree w/Bill.
    I've not heard of pearl being added to gel. Plenty of metal flake on about 20,000 bass boats around here though.

    I wanted to add that pearls definitely add an awesome glisten in the sunlight if that is the effect you are after. Here is my Vette with 3 colors of pearl in the paint. I painted it about 4 years ago - those are not photoshopped stars from the sunlight - . Bill

    Greg,
    I am amazed at your project - highly cool. If you are trying to get just the right red, you will probably have to do what I am doing with my Martini. I just met with a man yesterday who specialized in gelcoat repairs. He will be color matching my maroon color with a base color of red gelcoat and tinting it with a color tint kit from either Minicraft or Spectrum. Bill

    Thanks guys for the kind words. I'm always amazed at all the little things that pop up as you roll through a project. I'm glad that the 16 Baby is what I had the "connection" with from way back, 16 feet is about all I can handle! The bigger stuff that you all do is pretty amazing to say the least.

    Now on the gel front, several comments. We decided to prime the hull itself black, so right away the color I select will be darker when the gel is laid down. The boat will only run in salt water, so that has to be taken into account. Clint and I have gone back and forth on the reds to use and now that I have the samples I can wrap my head around what choice to make. Before we gel, I'll also have to decide what vinyl I want to use. Clint will gel the entire bottom red, right up to the rub rail. Above the rub rail will be white and we have not decided on gel or paint for that portion just yet. On the bottom, the thought with a pearl coat, was to add just a touch of depth and sparkle. This is my idea and I have no experience with this sort of thing but seeing as I am not going for a historical build like the TR or the Martini, I'm safe. I want timeless and classy, but thought a coat or two of pearl might provide a little extra pop when the sun hits it correctly. The rest of the time it will look like a Classic Red from back in the day. Not sure if a clear should then be applied on top of that to boot in a saltwater environment. I am a little worried that using clear might make the appearance upkeep a lot tougher, thoughts on that appreciated. On the pearl, I assume that the 009 boats are sprayed with that process, but heavy, and I don't want that effect, just want a little depth and sparkle kinda thing

    As an aside, any preferences on gel or paint for the deck and the hull's interior? Thanks

    Pearl is usually done in paint. There are different paint colors that sometimes require different techniques & products too. Some colors can have some pearl in s single stage, others it must be 2 stage & some must be done in a tri coat (2 different base coats & then the clear).. Some of it can be a real PITA, especially when blending if and when it is possible on some repairs.

    I dont think you will get the same result trying to suspend any type of pearl in a solid color gelcoat for the most part as the gel is too thick. It would have a tenancy to cling to the pearl and cover it without letting the sparkle thru that you are looking for..

    When you see pearl in gel coat, it is usually either A# a painted pearl over gel with a paint.. OR it is in-between layers of gel coat like metal flake, or suspended in a clear gel coat that is applied over your base color.. This can be a PITA like working with metal flake gel finishes as it is usually applied in the same fashion.

    If you were going to try to get a pearlecent type look or finish with a solid color gel coat rather than suspending pearl in a clear accordingly you may have problems. I would strongly try a test run in a large enough test panel first to see if it is going to give you the result you want.. I would NOT recommend the single stage gel approach if you are looking for the pearl effect.. At least not unless I have missed something in what you are asking about or unless you have a color that the gel manufacturer has actually recommended and produced with it in it already..

    Hope it helps you.. Jamie / Lakeside

    Pearl is actually made of plastic. It is mostly shot ontop of your basecoat and its a 3 step process. Basecoat, pearlcoat then Clearcoat I dont see any reason why it couldnt be applied to gelcoat as long as you use clear ontop of the color.
    I usually use House of Kolor Paints for my custom work. Pearl can be a bit tricky to lay down but as long as you know a few simple rules its pretty easy. House of Kolor has pearls in dry form. they are mixed with an intercoat clear to make it sprayable. If you use a siphon gun and dont have an agitatior in it simply use a couple ball bearings and drop them in the cup. when you use the gun it will keep pearl from settleing to the bottom. Also final coat of Pearl should be a "drop coat" Meaning you boost up the pressure and hold the gun about 2 to 3 feet away from the panel your painting at a 45 degree angle and dust it. This makes the pearl stand up and catch light best
    Good luck
    The sting of poor quailty far outlasts the Joy of a cheap price...
